BRIEF DESCRIPTION OF THE DRAWINGS

The novel features of the invention are set forth with particularity in the claims that follow. A better understanding of the features and advantages of the present invention will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the invention are utilized, and the accompanying drawings of which:

DETAILED DESCRIPTION

Embodiments of ultrathin eyeglasses are provided herein. The eyeglasses comprise a thin frame comprising two lenses connected by a nosebridge. A temple piece extends from each end of the frame. The temple pieces can be configured to fold flat or near flat against the frame and lenses such that there is little or no space between the temple piece and the frame in the folded configuration. The frame can comprise a plastic or polymer material and can be entirely molded from such a material. This design can allow for a frame with a very thin profile, for example less than 3.5 mm, enabling users to easily carry the glasses on a phone, in a purse, in a pocket, etc.

Currently available thin profile glasses generally do not comprise traditional temple pieces that are configured to fold flat or near flat against the frame. Such temple pieces can both provide stability to the user as well as provide a desired aesthetic affect. The enhanced stability enables the glasses to be worn during performance of numerous activities, not only limited to reading. The desired aesthetic affect can be due to the temple pieces resembling traditional, in-style temple piece design. Paper Glass, manufactured by Masahiro Sawada, utilizes curved temple pieces configured to fold above, instead of against, the lenses. While this produces a thin pair of glasses, the glasses do not have a traditional design, and may not appeal to as many users for that reason.

FIGS. 1A-D illustrate various views of an embodiment of eyeglasses 100. As shown in the top perspective view of 1A, and the front view of FIG. 1B, the eyeglasses 100 comprise a frame 102. The frame 102 comprises a first lens 104 and a second lens 106. The lenses 104, 106 are connected by a nosebridge 108. A first temple piece 110 extends from a first side of the frame 102, next to the first lens 104. A second temple piece 112 extends from a second side of the frame 102, next to the second lens 106. The first temple piece 110 is connected to the frame 102 using hinge 114. The second temple piece 112 is connected to the frame 102 using hinge 116. Either or both temple pieces can comprise a temple tip portion 118, 120.

In some embodiments, the frame comprises a polymer, such as polycarbonate. Other materials are also possible (e.g., Acetate, TR90, ULTEM, etc.). Such a material provides an aesthetic advantage as it can be used to create in-style designs, resembling glasses made of more traditional materials and still maintain a very thin profile. Such a material also provides the advantage of being able to be colored or patterned in a variety of styles. The color or pattern can be added using UV printing, which can provide the advantage of allowing a wide variety of styles to be produced economically. In some embodiments, a hardcoating process is used to make the lenses scratch resistant. Other coatings are also possible. For example, an anti-reflective coating and anti finger print coating can be applied as well. The frame can comprise a rigid material (e.g., the frame cannot be bent).

The lenses can comprise polycarbonate. In some embodiments, the lenses 104, 106 can be formed integrally with the frame 102. For example, the lenses and the frame can be molded as one solid piece (e.g., one solid piece of polycarbonate). In some embodiments, the lenses 104, 106 can be formed separately from the frame 102 and later attached to the frame.

In some embodiments, the nosebridge 108 comprises the same material as the rest of the frame (e.g., polycarbonate). In some embodiments, the bridge 108 can comprise a different material (e.g., nitinol). A combination of the bridge 108 and a portion 122 of the frame can be used to provide a comfortable fit on the nose without the use of any nose pads. In some embodiments, separate nose pads can be used to increase the friction with the nose on the edge of the frame that is in contact with the nose. Materials such as low durometer elastomers, grit embedded strip, micro texture on the frame can be used to increase the friction between the glasses and the nose. In some embodiments, micro texture is added by molding small serrations directly into the frame.

The hinges 114, 116 can comprise hinge points that are within the plane of the frame 102. This positioning can allow the temple pieces 110, 112 to lay flat against the frame 102 when in a folded configuration. In some embodiments, the frame 102 comprises the hinges 114, 112. Other configurations are also possible. In some embodiments, the entire hinge 114, 116 is within the plane of the frame 102 (e.g., as shown in FIGS. 6A-6D). In some embodiments, a portion of the hinges 114, 116 is formed integrally with the frame 102. In some embodiments, a portion of the hinges 114, 116 can be formed separately and attached to the frame 102.

In some embodiments, the temple pieces comprise a metal (e.g., nitinol). The temple pieces can be configured to fold flat against the frame. In some embodiments, the temple pieces are configured to fold near flat against the frame.

The hinges 114, 116 can comprise overmolded, curved inserts to increase the strength of the connection between the frame 102 and the hinges 114, 116. FIGS. 3A-3C depicts an embodiment of an insert 302 used to connect the frame 304 to the hinge 306 or strengthen the connection between the frame and the hinge. FIG. 3A provides a magnified view of the insert 302, while FIG. 3B shows the insert positioned in the glasses 100. The insert can comprise a metal (e.g., stainless steel) in some embodiments. The design of the overmolded metal insert piece of the hinge ensures a very high pull-out force without compromising on the durability of the molded material (e.g., polycarbonate). The wavy design and the rounded corners all serve to reduce stress concentration that might lead to stress cracking of the overmolded plastic material. The curved portion of the insert can comprise an undulating shape. In some embodiments, the insert comprises a sinusoidal or a zig-zag shape. The insert 302 can comprise a fillet 308, as shown in the magnified view of FIG. 3A. The length of the insert can be about 3.5 mm (or about 3 mm, about 4 mm, about 3-3.5 mm, about 3-4 mm, about 2-4 mm about 3-5 mm, etc.). The width of the insert can be about 1.5 mm (or about 1 mm, about 2 mm, about 1-2 mm, etc.). As noted above, the strength of the connection between the hinge and the frame can provide a high pull out force than can enable the temple piece to exert sufficient pressure to keep the glasses 100 properly positioned on a user's face while still allowing the glasses 100 to maintain a very thin profile. In some embodiments, the force exerted by the temple pieces can be sufficient to maintain the glasses in a stable position of the user's face. Other embodiments are also possible. For example, the hinges can comprise differently shaped inserts (e.g., straight inserts) or be connected to the frame in a different manner.

The temple piece can be attached to the hinge using screw 310, as shown in the blown up view of FIG. 3C. Other configurations are also possible (e.g., press fit pin).

In some embodiments, the temple pieces 114, 116 comprise temple tips 118, 120, shown in FIGS. 1A, and the side view of FIG. 1D. The temple tips 118, 120 can comprise a larger surface area than other portions of the temple piece, as shown in FIG. 1D. This larger surface area can help distribute some of the pressure exerted by the temple piece on a user's head. The temple tips 118, 120 can comprise a same material as the temple pieces 114, 116. In some embodiments, the temple tips 118, 120 comprise a different material from the temple pieces 114, 116. For example, the temple tips can comprise low durometer elastomers or thermos plastics. Materials like silicone or soft touch paint can be used to increase friction between the temple tips and the head and to match the color of the temple tips 118, 120 to the temple piece 114, 116.

FIGS. 2A-2D illustrate various views of another embodiment of eyeglasses 200. Unless otherwise described, features of the glasses 200 can be the same as those features of glasses 200 shown in FIGS. 2A-2D. As shown in the top perspective view of 2A, and the front view of FIG. 2B, the eyeglasses 200 comprise a frame 202. The frame 202 comprises a first lens 204 and a second lens 206. The lenses 204, 206 are connected by a nosebridge 208. A first temple piece 210 extends from a first side of the frame 202, next to the first lens 204. A second temple piece 212 extends from a second side of the frame 202, next to the second lens 206. The first temple piece 210 is connected to the frame 202 using hinge 214. The second temple piece 212 is connected to the frame 202 using hinge 216. Either or both temple pieces can comprise a temple tip portion 218, 220, best shown in the side view of FIG. 2D.

FIGS. 2E and 2F depict the glasses 200 in a folded configuration. The front view of FIG. 2E shows the glasses 200 comprising frame 202, lenses 204, 206, and bridge 208. Temple pieces 210, 212 are folded against the frame 202 and lenses 204, 206. The hinges 214, 216 connect the temple pieces 210, 213 to the frame 202. Temple tips 218, 220 are visible, angling down from the temple pieces. FIG. 2F provides a top view of the glasses 200 in a folded configuration, highlighting the thin profile of the glasses.

As shown in the top views of FIGS. 1C, 2C, and 2F the components of the glasses 100 can comprise a very thin profile. A thickness of the frame can be about 2 mm. Other thicknesses are also possible (e.g., about 1.5-3.5 mm, about 1.75-2.25 mm, about 1.8-2.2 mm, about 1.9-2.1 mm, about 1-3 mm, about 2-4 mm, etc.). A thickness of the temple pieces can be about 0.6 mm. Other thicknesses are also possible (e.g., about 0.5-0.7 mm, about 0.4-0.8 mm, about 0.3-0.9 mm, about 0.5-1.0 mm, etc.). In some embodiments, the thickness of the glasses in the folded configuration, with the temple pieces folded down over the lenses, is about 3.2 mm. Other thicknesses are also possible (e.g., less than about 3.5 mm, about 3-3.5 mm, about 3-4 mm, about 3.25-3.75 mm, about 3-3.4 mm, etc.).

In some embodiments, the thickness of the glasses in the folded configuration is about 2.6 mm. For example, the frame can have a thickness of about 2 mm. The temple pieces can have a thickness of about 0.6 mm each. In embodiments in which they do not overlap when in the folded configuration, the thickness of the overall pair of glasses is about 2.6 mm. In embodiments with the same dimension components, but where the temple pieces do overlap when in the folded configuration, the thickness of the glasses is about 3.2 mm.

In some embodiments, a volume of the glasses (e.g., glasses 100) in the folded configuration is no more than about 5 cm³ (e.g., about 4.9 cm³). Other volumes are also possible (e.g., about 4.9 cm3, about 4-5 cm³, about 4-6 cm³, about 4 cm³, about 6 cm³, etc.). In some embodiments, a surface area of the glasses (e.g., glasses 100) is about 95.5 cm² (e.g., about 94.45 cm². Other surface areas are also possible (e.g., about 90-100 cm², about 80-100 cm2, about 90-110 cm2, etc.). In some embodiments a mass of the glasses (e.g., glasses 100) is about 7.9 g (e.g., about 7.87 g). Other masses are also possible (e.g., about 7 g, about 8 g, about 7-8 g, about 7-9 g, about 7-10 g, etc.) In some embodiments, the volume of the glasses in the folded configuration is no more than about 6 cm3 (e.g., about 5.75 cm³). Other volumes are also possible (e.g., about 5.5 cm³, about 6 cm³, about 5-6 cm³, about 5-7 cm³, about 4-7 cm³, about 5-8 cm³, about 4-6 cm³, about 3-5 cm³, greater than 7 cm³, etc.). In some embodiments, a surface area of the glasses (e.g., glasses 200) is about 109 cm² (e.g., about 108.65 cm²). Other surface areas are also possible (e.g., about 110 cm², about 100-110 cm² about 100-120 cm², about 90-110 cm², about 90-120 cm², about 80-120 cm², greater than 120 cm², about 70-100 cm², etc.). In some embodiments a mass of the glasses (e.g., glasses 200) is about 8.9 g (e.g., about 8.895 g). Other masses are also possible (e.g., about 8 g, about 9 g, about 8-10 g, about 7-10 g, about 8-11 g, etc.)

In some embodiments, a weight of the glasses is less than about 10 g. For example, in some embodiments, the glasses weight about 9.8 g. Other weights are also possible (e.g., 8-10 g, 7-10 g, about 7 g, about 8 g, about 9 g, about 10 g, greater than 10 g, etc.). Such a light weight can make the glasses very convenient to carry, for example, on a smartphone, in a purse, or on a pocket. Additionally, the light weight can make the glasses very comfortable for a user.

In some embodiments, the glasses disclosed herein can comprise one or both aspherical lenses. Aspherical lenses of high index material can provide advantageously provide substantial vision correction while still maintaining a thin profile. In some embodiments, the high index material comprises an index of refraction of about 1.5-1.75 (e.g., about 1.53-1.74, about 1.5-1.8, about 1.4-1.8, about 1.4-1.75, etc.). In some embodiments, the aspherical lens comprises multiple powers, for example, for near reading at the bottom, intermediate reading, such as a computer screen, in a section above the near reading zone, and a distance zone with no refraction for looking straight ahead into the distance. Aspherical lenses can comprise a thicker section in a central portion of the lens and thin out towards the edges of the lens. The thinning out can present a problem, as the lens can become too thin towards the edges to provide a good connection to the frame of the glasses. The inventors of the current application discovered that adding additional material to the edges of the frame can advantageously strengthen the connection between the lens and the frame while still maintaining a desirable optical environment for a user of the glasses. This material is separate from the material forming the high index, aspherical lens and does not provide vision correction. It can comprise a transparent material added to provide stability to the lens and frame.

The thin profile of the glasses can allow the glasses to be placed into a very thin, easy to carry case, an embodiment of which is shown in FIGS. 4A-4E. FIG. 4A illustrates a top perspective view of the case 400. The case 400 comprises a top portion 402 and a bottom portion 404 shown in the bottom perspective view of FIG. 4E. The top portion 402 and bottom portion 404 are hinged together to open as shown in FIGS. 5A and 5B. A latch 406 can be used to hold the case in a closed position.

The case 400 comprises a very thin profile, shown in the front view of FIG. 4B and the side view of FIG. 4D. In some embodiments, a thickness of the case is about 4.5 mm. Other thicknesses are also possible (e.g., 4.35-4.5 mm, 4.25-4.75 mm, 4.2-4.7 mm, 4-4.5 mm, 3-5 mm, 3-6 mm, 2-5 mm, 3 mm, 3.2 mm, 3.5 mm, etc.).

The top and bottom portions can have an ovular shape, as shown in FIGS. 4A-4E. Other shapes are also possible (e.g., rectangular). In some embodiments, the case can be configured to attach to the back of a smartphone (e.g., using double-sided tape, Velcro, sliding groove, snaps, etc.). The thin profile of the case can advantageously add minimal thickness to a smartphone, allowing a user to carry the glasses case easily with other every day items. The case can comprise Brushed Aluminum with anodized treatment or stainless steel with appropriate coating and a polycarbonate/ABS core.

FIG. 5A shows an embodiment of a case 500 in an open configuration with the top portion 502 and the bottom portion 504 separated. As shown, the inside of the top portion 502 and the bottom portion 504 comprise depressions 508, 510 shaped to receive glasses 512 (FIG. 5B) such as those disclosed herein in a folded configuration. The depressions that are shaped to match the glasses can provide protection for the glasses, preventing them from being jostled within the case. Because of the thin profile of the glasses, the case can provide this protection while still maintaining a very low thickness (e.g., about 4.5 mm). As shown in FIG. 5B, there is extra room in the depressions, around the glasses 512. This shape of the depressions allows the case to carry various different styles of glasses, allowing manufacturing of only one case for various styles of glasses. In some embodiments, the material forming the depressions comprises Polycarbonate/ABS.

FIGS. 6A-6D illustrate embodiments of a hinge that can be used with the glasses disclosed herein. As shown in FIG. 6A, the hinge 600 is formed from and at an end of the temple piece 602. The end of the temple piece is formed into a loop 604. A bearing (e.g., a low friction plastic bearing such as Delrin) can be inserted into the loop (not shown). The hinge assembly 600 is inserted into a pocket 620 (FIG. 6B) molded in the frame 622. A hole is drilled and a pin inserted through the frame and the bearing material to capture the temple piece and the bearing. The temple piece and hinge assembly can comprise a thin yet strong material (e.g., stainless steel). This hinge configuration allows all or most of the hinge to be within the plane of the glasses frame and lenses, which minimizes the overall thickness of the glasses. In this configuration, the total thickness of the glasses with a frame of 2 mm thickness and temple pieces with 0.6 mm thickness would be 2.6 mm substantially throughout the assembly except for the place where the temple pieces cross each other. In some embodiments, the temple pieces can be configured to not overlap in the folded configuration, and the thickness is 2.6 mm throughout the glasses.

FIG. 6C illustrates a front view of an embodiment of eyeglasses 630 using the hinge assembly 600 of FIGS. 6A and 6B. Only one temple piece 602 is shown connected to the frame 632. Pocket 620 is shown on the other side of the frame 632. FIG. 6D shows a top view of the glasses 630 showing how flat the temple piece folds against the frame.

When a feature or element is herein referred to as being “on” another feature or element, it can be directly on the other feature or element or intervening features and/or elements may also be present. In contrast, when a feature or element is referred to as being “directly on” another feature or element, there are no intervening features or elements present. It will also be understood that, when a feature or element is referred to as being “connected”, “attached” or “coupled” to another feature or element, it can be directly connected, attached or coupled to the other feature or element or intervening features or elements may be present. In contrast, when a feature or element is referred to as being “directly connected”, “directly attached” or “directly coupled” to another feature or element, there are no intervening features or elements present. Although described or shown with respect to one embodiment, the features and elements so described or shown can apply to other embodiments. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature.

Terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. For example, as used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items and may be abbreviated as “/”.

Spatially relative terms, such as “under”, “below”, “lower”, “over”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal” and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.

Although the terms “first” and “second” may be used herein to describe various features/elements (including steps), these features/elements should not be limited by these terms, unless the context indicates otherwise. These terms may be used to distinguish one feature/element from another feature/element. Thus, a first feature/element discussed below could be termed a second feature/element, and similarly, a second feature/element discussed below could be termed a first feature/element without departing from the teachings of the present invention.

Throughout this specification and the claims which follow, unless the context requires otherwise, the word “comprise”, and variations such as “comprises” and “comprising” means various components can be co-jointly employed in the methods and articles (e.g., compositions and apparatuses including device and methods). For example, the term “comprising” will be understood to imply the inclusion of any stated elements or steps but not the exclusion of any other elements or steps.

As used herein in the specification and claims, including as used in the examples and unless otherwise expressly specified, all numbers may be read as if prefaced by the word “about” or “approximately,” even if the term does not expressly appear. The phrase “about” or “approximately” may be used when describing magnitude and/or position to indicate that the value and/or position described is within a reasonable expected range of values and/or positions. For example, a numeric value may have a value that is +/−0.1% of the stated value (or range of values), +/−1% of the stated value (or range of values), +/−2% of the stated value (or range of values), +/−5% of the stated value (or range of values), +/−10% of the stated value (or range of values), etc. Any numerical values given herein should also be understood to include about or approximately that value, unless the context indicates otherwise. For example, if the value “10” is disclosed, then “about 10” is also disclosed. Any numerical range recited herein is intended to include all sub-ranges subsumed therein. It is also understood that when a value is disclosed that “less than or equal to” the value, “greater than or equal to the value” and possible ranges between values are also disclosed, as appropriately understood by the skilled artisan. For example, if the value “X” is disclosed the “less than or equal to X” as well as “greater than or equal to X” (e.g., where X is a numerical value) is also disclosed. It is also understood that the throughout the application, data is provided in a number of different formats, and that this data, represents endpoints and starting points, and ranges for any combination of the data points. For example, if a particular data point “10” and a particular data point “15” are disclosed, it is understood that greater than, greater than or equal to, less than, less than or equal to, and equal to 10 and 15 are considered disclosed as well as between 10 and 15. It is also understood that each unit between two particular units are also disclosed. For example, if 10 and 15 are disclosed, then 11, 12, 13, and 14 are also disclosed.

Although various illustrative embodiments are described above, any of a number of changes may be made to various embodiments without departing from the scope of the invention as described by the claims. For example, the order in which various described method steps are performed may often be changed in alternative embodiments, and in other alternative embodiments one or more method steps may be skipped altogether. Optional features of various device and system embodiments may be included in some embodiments and not in others. Therefore, the foregoing description is provided primarily for exemplary purposes and should not be interpreted to limit the scope of the invention as it is set forth in the claims.
